DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent N 0. 659,324, dated October9, 1900.

Application filed February 26, 1900. serial No. 6 ,606. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES H. SAWYER, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Draft-Equalizers, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawing, forming a part hereof.

My invention has relation to improvements in draft-equalizers; and itconsists in the novel construction and arrangement of parts more fullyset forth in, the specification and pointed out in the claims.

In the drawing the figure represents a gen-v eral plan of the equalizer.

effectively distribute the load equally among the several draft-animalsattached to the devlce.

A further object is to minimize the breaking strain upon the member orbase-bar immediately connected to the load to be drawn.

While the present equalizer is specially designed to be used inconnection with plows and other 'agriculturai implements, it is apparentthat it could be used with other loads or vehicles to be drawn.

In detail the invention may be described as follows:

Referring to the drawing, 1 represents a base-bar having its point ofattachment to the plow or other load (not shown) at the point 0, saidpoint being in the line of draft that is, the line about which all theforces are equalized in the drawing of the implement in adirect line.Attached at one end of the basebar by means of a clip and link orotherwise is a singletree 3, and at the opposite end is attached anevener or distributer bar 2,a similar intermediate evener or distributer2 being hung from a point 4 along the basebar, the adjacent ends of thedistributers 2 2 being linked or coupled together, andfrom their coupledends is hung a singletree 3", the coupled arms of the distributers beingthe longer. The ends of the short arms of the distributers have hungtherefrom the singletrees 3 and 3". As seen from the drawing, all thesingletrees are equidistant from the base-bar, three of them beingsuspended from the distributers 2 2 and only one singletree, 3, beingconnected directly to the base-bar. The point of suspension orattachment of the singletree 3 is nearer the point C than is theopposite extreme singletree 3, which, as clearly shown, has its point ofattachment at the end of the short arm of the outer distributer-bar 2.Accordingly in order to properly assist the animal hitched to singletree3 it is necessary to make the point of attachment 4 of the intermediatedistributer 2 on that side of the point C which is nearer to or towardthe singletree 3. By the present arrangement also the animals hitched tosingletrees 3 and 3 pull at the base-bar 1 from the point 4, therebyminimizing the danger One object of my invention is to construct. adraft-equalizer which will positively and 0f the bar bending about itspoint of attachment O, and hence under my preser'itarrangement the bar 1may be made much lighter and of smaller cross-section than is the casein the majority of draft-equalizers. The distance between the center ofdraft 0 and the point of attachment of the outer singletree 3 with thebase-bar is just sufficient to permit the animal coupled to saidsingletree to tread in the path of the furrow left by the plow duringany previous plowing operation, and as it is desirable that the animalcoupled to this singletree shall be removed this distance it is apparentthat my present device presents advantages over any other form ofdraftequalizers. This distance brings the outer horse on that sidenearer the point of draft than in any other equalizer known to me. It isfurther apparent that my device is totally devoid of any sidedraft-levers or combination of levers or offsets, the draft being al-Ways at right angles to the general direction of the base-bar.

Having described my invention, What I claim is r 1. A draft-equalizercom prisinga base-bar, a'singletree coupled thereto at a certaindistance from the point of draft thereof, a distributer coupled theretoat a certain distance on the opposite side of the point of draft, and anintermediate distributer coupled to the base-bar at a point on that sideof the point of draft which is nearer the point of attachment of thesingletree to the base-bar, substantially as set forth.

2. A draft-equalizer comprisingabase-bar,

singletree coupled at one end thereof, a distributer at the oppositeend, and an intermediate distributer coupled to the base-bar and havingits point of attachment on that side of the point of draft of thebase-bar which lies nearer the singletree, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
